TORONTO, ONTARIO, CANADA, A CORPORATION FEEDING DEVICE FOR COMPUTING MACHINES.

Application sied Marcil 14, 1923. serial No. s254151.

This invention relates to an imprdvement in printing machines, and with respect to its more specific features to feeding mechanisms for such machines.

An object of this invention is to provide a new and improved means for supplying a duplicate record strip to writing position upon a platen from a. single roll.

A further object is to provide new and improved means foruse with a platen, by which a single web may be fed to a machine y and folded longitudinally as it is fed.

A further object is to provide an arrangement whereby a strip having transfer material upon a portion of one face thereof may be so arranged as it is fed to a machine as toA bring thesaid transfer material in position to make a manifolding record upon another portion of the strip.

Other objects will be in part obvious and in part pointed out hereinafter.

The invention accordingly consists in the features of construction, combinations of elements and arrangement of parts which will be exemplified in the construction hereinafter set forth, and the scope of the applicatio-nof which will be indicated in the following claims.

\v u" The invention is adapted to supply a multiple layer strip for manifolding purposes and in its specific embodiment, to supply a double .layer strip to adding machines, typewriters, or the like. It therefore specifically illustrated in that connection.

In the accompanying drawing forming a part of this specification wherein similar `reference characters refer to similar parts throughout the several views,

Figure 1 is a side elevation of a printingl machine, provided with the improved feeding mechanism,

Fig. 2 is a front elevation, Fig. 3 is a plan view of a' portion of the strip, y

Fig. 4 is a plain view of the strip folding mechanism, Fig. 5 is a side elevation of the same, Fig. 6 isa side viewshowing the improvement applied to the printing machine of thel typewriter class, a part only of the machine being shown,

Fig. 7 is a rear view of the same,

The embodiment of the invention shown inFigs. 1 to 5 inclusive, is a printing machine of the adding machine type, the said machine being indicated generally at 1. It has the usual setting keys 50, which properly arrange the type bars for printing, and they are operated to print by means of a lever 3 which is pivotally mounted, to swing longitudinally of the machine. The frame is composed of laterally spaced Y`side plates 2, which are connected by shafts 4, 4 and 5, the latter shaft 5 supporting the platen cylinder indicated at 6, and having the usual knobs 7 for manipulating the cylinder.

`The shaft 4* is stationary and supports the The line of partial separation also prevents, i

crumpling and bunching of the folded edge of thestrip while it is passing around the platen, and said line provides a crease upon `which the fold may be easily made. The

strip is supported by a suitable reel indicated at 11, and it is so supported that when the plain portion of the strip is folded beneath the transfer faced portion, the said transfer 4face will be between the strips, so that when matter is impressed upon the upper face of the folded strip, there will be a duplicate on the lower fold or plain portion of the strip. A suitable tensioning device is provided for the reel, the said device having also the function of guiding the strip and holding it in position on the reel. In the present instance the devicey comprises a plate 12 having its.

ends bent laterally to form flanges as shown at 13, and one of the flanges is provided with an extension 14, having an angular portion 15 which laps upon one of the p lates 2, and is ivoted thereto as indicated at 16. The bod)y 12 of the plate rests upon the strip upon the reel, as shown in Fi 1, with the flanges 13 depending at the en s of the reel,

I and the plate not only tensions the stri on the reel, but also prevents lateral shi 'ting of the coils of the strip.

The folding mechanism which is supported by the shaft 4 comprises a plate A17 of trapezoidal shape, and having secured there to an angle plate 18, which carries a bearing 19 en aging the sha-ft 3. A set screw20 is threa ed through the bearing and engages the shaft, to -hold the bearing in adjusted receive the full width of the strip, and the engage over the opposite side edges thereo as the paper passes over the plate 21. The

. foldinguplate 17 has one folding edge 22 substantially at right angles to andon one side of the center line of the strip and another folding edge 23 making an acute angle with and'lying on the other side of the center line. `Preferably the latter edge 23 lies under the half of the strip carrying the transfer material and the former edge 22 lies under the other half. As shown the edge 22 is at right angles and the stri 23 at an angle of about 30. A folding nger 24 is supported bythe shaft 4 and the said fin er'extends into a position to engage the plain face of that portion of the strip which carries the transfer material and to fold the same beneath the other portion'of` the strip, as the other portion is drawn sharply across the edge, thusbrinlging the transfer material which, after fo ding, is upon the upper face of the lowermost portion of the strip,

y into contact with the lower face of the upvpei-'most portion of thev strip, the fold being on the'line .of partial separation, as shown in Figs. 4. and` 5. Referring to Figs. 2, 4, and 5, it will be noticed that the folding iinger 24 is connected to the end o`f the shaft 4,

outside the plate 2, and that it extends inwardly and frwardly to and beyond the central line of the strip, at which point itis provided with 'a gentle curve, for engaging i the paper to smoothly turn under the same.

The yfolded strip passes over a guard 25 and beneath the platen roll, being held against the roll at the front of the roll by a holding roller 26 which is journaled in supporting arms 27 on the frame. From the supporting roller 26, the strip passes upwardly adjacent to the printin mechanism,.which impresses the matter to printed thereon.

The operation of the deviceis as follows: The reel being provided with-a strip f paper of the character described,'the end of the strip is passed over the plate 21, with ,thevedges o f the strip beneath the guides 22 and 23. That edge of the strip not provided with transferl material is folded beneath the other edge after which the folded strip is drawn over Vthe guard and beneath the platen vroll. When now the pla-ten roll is operated to feed the strip of paper indicated at 32 by I the carriage shifting lever shown at 33, orv by the knobs 34 on the ends of the roll.l Thev carriage is laterally translatable, as is usual,

and the movement of translation in one dithe folder indicated at 37 which 1s the same as that shown in Figs. 4 and 5, is supported by a rod 38 forming a part of the frame 36. The strip 32 of paper is of the same charac'- ter as that shown in Fig. 3, and as it is fed by the platen roll, the strip is folded upon itself so that whe printed upon, there will be an original an a duplicate copy. The

printing mechanism not shown, cooperates with'the laten roll. A tensioning device 40 is provlded for tensioning the strip, the said device coopera-tino' with the paper on thereel, and correspon ing to that shown at 12 in Fig. 1. The machine in either instance prints a duplicate, and after the print is completed, the duplicate may bev separated from the original if desired. The strip is placed on the reel with the face having the transfer material inward and adjacent to the guidev 23. As the strip passes through the older, the face having the transfer material is turned beneath the plain portion, but as the strip passes beneath the platen roller, and'moves in front of the same,.the plain portion is at the rear, that is adjacent to the platen roll.

As many changes could be made inthe above construction and many apparently widely different embodiments of this invention could be made without departin from the scope thereof,- it is intended that a l mat-y t tendedfto cover all of the generic and specific includin features of the invention herein described, and all statements of the scope of the invention, -which, as a matter of language, might be said to fall therebetween. p
